AM3356: USB0 and USB1 VBUS

Eby Jayan

Part Number: AM3356

We are currently using the USB0 of the AM3356 in our design . If we are using the USB1 interface also , can we connect both USB0 and USB1 VBUS together ?

Hello Eby,

According to the section 16.2.1 VBUS Voltage Sourcing Control in AM335x TRM , the USB controllers uses the USBx_DRVVBUS pin to control the external charge pump/power logic on its respective VBUS line.

So, kindly refer the AM335 EVM for USB0_VBUS and USB1_VBUS connection.

Below I have also captured the screen shot of the section from TRM.
